The STIHL RMA 510 is a battery-powered push mower for small to medium-sized lawns. A steel deck with a 20-inch cutting width, adjustable handlebar and large rear wheels combine dependable cutting with easy handling. The catcher collects clippings, and a storage slot holds a spare battery for a quick manual change when needed. Quiet operation, instant starts and no exhaust emissions during use simplify routine lawn care. The unit-only mower excludes the battery and charger. AP System tools accept both STIHL ALLPRO and AP batteries. Run time and coverage vary with the battery, charge, mowing conditions and operator technique. The listed replacement blade is the 21-inch blade, part 6372 702 0100.
